The system as described produces an inverted V-beam and may be used to enable the pilot of an aircraft 7, Fig. 2 (not shown), to compute his elevation and land along a predetermined path, or, to produce the height dimension in a 3-dimensional radar display, Fig. 9 (not shown). In the first application the ground equipment 1 comprises a transmitter 2 feeding two antennµ 4 and 5 via a power divider 3. Antenna 5 produces a vertical fan beam intercepting the said sphere in a great circle CPG, Fig. 3 (not shown).

The two antennµ are rotated together around a vertical axis such that the two beams intercept the aircraft 7 at times spaced by an amount dependent on the elevation of the aircraft. The airborne equipment comprises a receiving antennµ 8 feeding a timer 10, angle of descent computer 11 and display 12. In the second application, Fig. 9 (not shown), the same antennµ are used, but the receiving equipment 52 and 58 receiving echos from aircraft 56 is provided at the ground station together with the computer 61. The vertical antennµ 5, Fig. 4, and Figs. 5, 6, 7 and 8 (all not shown) comprises a waveguide feed 25 having 63 radiating slots in the side facing the reflector 24, spaced either side of the centre line of said side to produce a beam having a width in azimuth of 1À5 degrees, and a distorted parabolic reflector 24 producing a vertical fan beam extending in elevation from 6 degrees to 75 degrees. The slant antenna 4 is rotated from the horizontal by an angle of 20 degrees, representing angle C, and through a clockwise horizontal angle of 10 degrees from antenna 5 (looking down in plan view) and comprises a waveguide feed 23 having 110 radiating slots, and a distorted parabolic reflector 22. The distribution of the slots in feed 23 is such as to cause the curvature of the beam cross-section, and produce a beam width in azimuth of 1À5 degrees. Tables are provided giving the slot distribution in each waveguide and the profile of each antenna reflector. Three shaped slant beams may be used together with one vertical flat beam to provide additional information. Electronic scanning may be used for the rotation in azimuth.

The resin granules are spread or dropped on to a carpet fed from a roll on to a conveyor belt which may be vibrated to spread the granules evenly on the carpet. The assembly is then fed into an oven where the granules are spread or dropped on to a carpet fed from a roll on to a conveyor belt which may be vibrated to spread the granules evenly on the carpet. The assembly is then fed into an oven where the granules are heated and melt to become embedded in the fibres of the carpet. A further layer of granules containing a blowing agent may then be spread or dropped on to the still hot sheet of flexible backing, vibrated, and heated in a further oven to form a layer of foamed resin on the back of the flexible backing. The vinyl chloride resin with blowing agent may be applied as a powder and compacted before it is heated. A layer of plastisol may be applied with a doctor blade to the back of the carpet before the application of the vinyl chloride resin granules. The granules may comprise a vinyl chloride homopolymer or a vinyl chloride and vinyl acetate copolymer or a copolymer of vinyl chloride with a monoethylenically unsaturated monomer such as ethylene, propylene, cetyl vinyl ether, dialkyl maleate, acrylonitrile or styrene, with a plasticiser such as dioctyl phthalate, stabiliser, a pigment, or a filler such as calcium carbonate.
